Twilight grump
Kristen Stewart has revealed the reason behind her famous frown.
âI get defensive and that has probably perpetuated peopleâs idea of me never smiling,’ she explains.
The 20-year-old adds: âI kind of shake my leg too, so people think Iâm always uncomfortable.â
But the actress also says she is finally getting to grips with the unwanted attention surrounding her and the series co-star, Robert Pattinson.
